Themes from 2016 CORF Annual Meeting
4
Proven formula: Make spectrum available Encourage and protect innovation-driving competition Stay out of the way of technological development and details of
implementation
Spectrum: Flexibility: FCC will not designate the 5G band or bands Trifecta: Importance of low, mid and high band spectrum
Opening of High Band Spectrum
Spectrum Allocations
10.85GHz of Spectrum added for mobile Licensed Bands (3.85GHz):
27.5-28.35 GHz; 37-38.6 GHz; 38.6-40 GHz;
Unlicensed Bands (7GHz): 64-71 GHz
Service Rules
Part 30: Upper Microwave Flexible Use Service (UMFUS)
Geographic Area Licensing, Area Size, Band Plan, License Term, Overlay Auctions
Technical rules Performance Requirements Ensure cyber protections
considered from the start
Spectrum Frontiers Report and Order and Further Notice of Proposed Rule Making
Adopted by the Commission July 14, 2016
Further Developments
• Petitions for Reconsideration: – Generally strong support for FCC actions – Revisions requested for:
• 28 GHz: Greater flexibility for earth station deployments • 37 GHz: Sharing with federal systems • 39 GHz: Adjust sharing criteria regarding terrestrial power limits
and satellite pfd limits • Many other details
• Much industry activity: market transactions • Continued industry testing, R&D, standardization, trial deployments
Next Steps
Address petitions for reconsideration later this year
Determine which additional bands to make available among 24.25-24.45 GHz; 24.75-25.25 GHz; 31.8-33.4 GHz; 42-42.5 GHz; 47.2-50.2 GHz; 71-76 GHz; 81-86 GHz; and, bands above 95 GHz
Continue support for R&D through new experimental program licenses
Continue work looking towards WRC-19 8

• Band Class 66 (AWS-3) is already implemented in several LTE phones
• Limited testing is on-going as it takes time for DOD systems to relocate
• Supplemental downlink is available as needed
Federal Incumbent Systems: • Fixed Point-to Point Microwave • Military Tactical Radio relay • Air Combat Training System • Precision Guided Munitions • Tracking, Telemetry & Commanding • Aeronautical Mobile Telemetry • Video Surveillance • Unmanned Aerial Systems • Other Systems

Recent Developments
• Second Report & Order & Order on Reconsideration - April 28, 2016 – Affirms regulatory approach – Allows increase in the power level for non-rural Category B CBSDs – Allow a single PAL to be issued in License Areas located in Rural Areas in the absence
of mutually exclusive applications – Establishes Engineering-based approach for determining when Priority Access License
area in use – Adopts a robust, flexible secondary market for Priority Access Licenses – Balances the expanded access for wireless broadband operators with the need to
protect fixed satellite service operations
• Certification of SAS Administrators and ESC – Public Notice December 2015 established procedures for submission and review of
proposals from prospective SAS Administrators and ESC operators – February 2016 meeting of prospective SAS Administrator sand ESC operators – “First Wave” Proposals filed in May 2016 – April 2017 - PN announces how 3650-3700 MHz incumbents file for grandfathered,
protected status – Separate PN announces a second-wave deadline to apply for approval to serve as
SAS and ESC administrators
SAS & ESC Approval Process
Similar to TVWS
Overseen by WTB/OET; close consultation with NTIA and DoD
Applications to include all information in PN
Evaluate all of the “first wave” proposals
Release list of those conditionally approved
Assess and test each conditionally approved SAS and ESC

TV Incentive Auction 600 MHz Band Plan
Repacked TV Guard Medical Duplex Gap Repurposed Band Telemetry & For Wireless Radio Astronomy Auction
First time the Commission has needed to develop band plans without knowing how much spectrum will be available!
Technical Pillars of TV Incentive Auction
TV Study Software Used to predict Coverage & Population Served
Constraints on Repacking Stations
Controlling Inter-service Interference Repacking
Optimization
Can’t assign same channel – too close
OK to assign same channel – far apart
Reorganize remaining stations in most efficient way that recovers the most spectrum at the least cost - - akin to defragmenting a hard drive
Incentive Auction Closed
• Bidding in the auction closed on March 30, 2017 – preserves a robust broadcast TV industry while making valuable “low-
band” airwaves available for wireless broadband – repurposes 84 megahertz of spectrum – 70 megahertz for licensed use
and another 14 megahertz for wireless microphones and unlicensed use – yields $19.8 billion in revenue - including $10.05 billion for winning
broadcast bidders, more than $7 billion to be deposited to the U.S. Treasury for deficit reduction
• April 13, 2017 Commission PN formally closes auction – Begins 39-month period for some TV stations transition to new channel
assignments
5GHz Band
22
• WRC-12 R&O allocated 5030-5091MHz for UAS CNPC • Note that AeroMACS allocation is at 5000~5030MHz and 5091~5150MHz • DSRC/UNII-4 testing is on-going
UNII-2B: 5350 – 5470 MHz
• Very difficult sharing scenarios – Includes federal
plane/ship/terrestrial radars & earth exploration satellite
• US proposed to continue international work for WRC-19
• Work group established: – FCC/NTIA/DoD/NASA – Considered Ix protection studies &
sharing approaches
• Have not been able to identify a way forward at this time
Aeronautical radar must pick up weak reflected signals from far away
Wireless networks must “hear” very weak signals from radar
Aggregate Interference
Balance detection vs falsing
• IEEE Tiger Team Proposal: Re-channelization • Dedicated DSRC spectrum
– Open only the lower part of the spectrum to UNII devices – Leave 20MHz or 30MHz dedicated spectrum for DSRC high-avail channels – Share the Channel 173 and 177 between DSRC service channels and UNII devices
• For the shared spectrum – Encourage 20MHz DSRC service-channel operation
• Would allow for more effective detection of the DSRC signals
– Develop sharing solutions in IEEE • Service channels can also use 802.11n/ac in any 5GHz band for service applications
UNII-4: 5850 – 5925 MHz

LTE-U, LAA & Wi-Fi
• LTE – Long Term Evolution: Technology designed to operate in licensed spectrum
• LTE for unlicensed spectrum: – Focus on U-NII 1 & 3 (no DFS)
• OET/WTB sought to better understand technologies
• Wi-Fi Alliance Co-Existence Test Plan • The FCC approved first LTE-U Devices
– Tested to show they meet FCC rules – Though successful evaluation under co-existence plan, this is not an FCC requirement
Wi-Fi: Carrier sense multiple access with collision avoidance (CSMA/CA)
